Tetrathiafulvalene(TTF) is an excellent electron donor, therefore it has been used in amyriad of molecular conductors and supramolecular application. The main focus of this review is on the recent progress of synthesis and application of various triazole-based TTF derivatives(TTFs) mainly including traditional tetrathiafulvalene, tetrathiafulvalene vinylogue and extended tetrathiafulvalene via click chemistry. Assisting copper(I)-catalyzed azide-alkyne cycloaddition reaction(CuAAC), the general aspects of T...
